REL B3 connecting to Linn Klimax Solo help...

Hi All,

I cannot get any output using a 20hz tone on my demo REL B3. Its connected to the High Level unbalanced input with the earth going to my Source ground plug and the RED wire to my Right Positive Monoblock and the Left wure to my Left Positive Monoblock

The amplifiers are Linns Klimax Solo 500. Can anyone assist in determing the right way to connect this in a 2channel system only?

My Linn pre, source and monoblocks all used balanced cables.

Thanks

If the Klimax DS does not have chassis ground connected directly to circuit ground, and it very well may not, using that ground could very conceivably be causing the problem. I would suggest proceeding as in my initial response.

Also, if you connect the sub's ground to one of the speaker leads, and use a test tone at a higher frequency that is more easily audible (e.g., 50 or 60 Hz), what happens?

Hi Al,

I have connected the subs ground to the speaker lead and I get the horrible output noise with no cone movement at 45% gain... The unit under any connection method wont go over 45% gain. I did try 40 and 50 hz with the speaker lead connection. Same issue

The cone barely if at all moves on any setting. Spoke to the distributor who said there should be alot of cone movemen on either high level or low level inputs and that it appears faulty.

Ok, then it does appear likely that it is faulty.

But when it is replaced or repaired, I would still suggest that to assure optimal sonic results you connect to circuit ground on the preamp, as determined per my initial response.

Hi Al

How do I do that on my pre, it has no ground plug....

Not sure what you mean by a ground plug. But in any event, proceed as I described in my initial response:

If there is a binding post or other terminal on the rear marked "earth ground," or similar, use a multimeter as I described to determine if that is connected directly to circuit ground. If it is, connect to that binding post or terminal.

If there is no such binding post or terminal, use the multimeter to determine if a chassis screw is connected directly to circuit ground. If it is, loosen that screw, wrap the ground wire from the sub around it, and tighten down.

If neither of the above applies, solder the ground wire from the sub to the ground sleeve of an RCA plug, as I described, with nothing connected to the center pin of the RCA plug, and insert that RCA plug into any RCA jack on the preamp.
